Working with what you have.
WHY IT MATTERS
Improving an existing page that already receives traffic frequently produces more than writing a new one.
WHAT TO UPDATE
Pages receiving traffic but few enquiries Pages losing position Anything containing out-of-date information
WHAT TO CHECK IN AN OLD ARTICLE
Prices and figures Anything describing how something works Links that no longer function Whether it still reflects what you do
WHAT TO ADD
Questions readers ask that the article does not answer Recent examples A clearer next step
WHAT TO REMOVE
Padding Anything no longer true
WHEN TO UPDATE RATHER THAN REWRITE
When the subject is unchanged and the page has established position.
Updating preserves that. Replacing it loses it.
WHAT TO DO WITH GENUINELY OBSOLETE CONTENT
Update, redirect to a replacement, or mark clearly as historic.
Not simply delete, if it has traffic or links.
HOW OFTEN
Review your main pages annually.
